To all whom it may concern: 7 Be it known that I, EUGENE R. Pnoir'r, acitizen of the United States, residing at Baltimore, in the StateofMar'yland, have "invented certain new and usefullmprove- 'merits in.Hot Water vHeating Systems, of which the following is a specification.

This invention'relat'es to improvements in hot-waterheati'ng systems,and has for-its object to provide adevice'which is simple;

in construction and eificient in operation, and

whichcan readily. be applied to any ,furna'ce, or-heating plant.

The invention consists of the novel construction and arrangementofth'eparts and combination'ot'parts hereinafter more fully fat setforth in the following specification and pointed out in detail in theappended claims.

lln'the accompanying drawings.-

v pipes, the feeding-and circulation of the water beingindi'cated by thearrows. i

' -Referring to the accompanying drawings,

forming, part ofthis specification, and in which like reference numeralsdesignate like parts throughout. the several views thereof, '1designates the furnace in which the vertical pipe 2 is placed and whichextends down, into'the firebox of said furnace. This 'pipe 2,-isconnected to andfcoinniunic'ates with the pipe 3, which latter projectsthrough the furnace and has apipe 4 connected to and communicatingtherewith, which said pipe t carries the'heated water to the radiator 5,and the return water pipe 6 leadingfrointhe' said radiator 5 to andcommunicatingwith, the pipe 3. The feed water pipe 7 is also. connectedto andcommunicates with the pipe 3; 1 Said feed water pipe 7 passesaround the furnace '1 and is connected with any source of supply, andmay also be connected to an expansion tank if desired. The pipe thesupply or feed pipe 7 and the other end extending down into andterminating near the lower end of the pipe 2. The said pipe 2 isprovided with a plug 10 'in-itslower end and a drain pipe 11. a

The pipes described are for heatmg one Figure 1 is a sideele'vation of afurnace, partly brokenqaway'and showing. my inven- Specification ofLettersPatent. t nt d n 11, 5 Application nee February 14,1817; SerialNo. 148,474.

radiator ,and the same are duplicated for each radiator to be heated. p

The operation of the device is'as follows: The pipe 2 is down in thefire-box of the furnace 1 and as the water flows from through the smallpipe 9 down into the pipe 2'where it is heated and then upthrough pipe 3to pipe 4' where it'flow's to the radi ator 5. As the water cools itfiowsback through the return pipe 6 to the pipe'3 on the'opposite side.of the partition 8 and then passes through thesmall pipe 9 to the pipeQ'Where it is reheated and'passes to the radiator5. Having thusdescribed my invention, what Iclaim is:

'60 the pipe 7 into'the pipe 3 the latter being closed by the partition8 the water will flow 11. The combination with a heater and a radiator,of a pipe projecting into the firebox of said heater, a pipe connectedto the first mention'edpipe and leading tothe ra diator,"a pipeleadingfrom the radiator to and. communicating with the first-mentioned pipe,a.'supply pipe connected to said firstmentioned pipe, a partition insaid firstmentioned pipe between the supply pipe and the. pipe leading.to the: radiator, a small pipe within the, first-mentioned pipe havingone end projecting through said partition and theother end projectingdown to near the bottom otthe pipe in the fire-box.

2. .The combination "with a heater and 'a radiator, of a pipe projectinginto the fire ,-box of'said heater, a'pipe connected to thefirst-mentioned pipe and leading to the. 1 a diator, a pipe-leading fromthe radiator to and communicating with the first-mentioned pipe, asupply pipe 'connected'to said first mentioned 'pipe between the.pipeleading to the radiator and the pipe leadingfrom the radiator, a.partitionin said first mentioned pipe between the supply pipe and the.pipe leading tothe radiator,"and a small pipe within said firstmentioned ;pipe-. and

having one end projecting through saidIparj tition adjacent the supplypipe'and the other L end projecting down to hear the bottom of' the pipe'in the fire-box.
